Samsung EB575152LU Li-ion Battery for Samsung i9000 Galaxy S / i9001 Galaxy S Plus / i9003 Galaxy SL / B7350 Omnia (1650mAh) (Accessories)
The battery creates what can make it and is of course good, but it does not come close to third party, since it precisely corresponds to the capacity of her only one original. Full power would sometimes cool, so 12000mAh or so ;-)
